Proof step 31 from proof validrefs-newref (previous step)

validrefs(str, refs, ty, st), r ∈ refs, newref(r, st) ⊦ r = jvmref

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ validrefs(str, [], ty, st)
Proof step 30:
∀ str, ty, st, r. validrefs(str, acc, ty, st) ∧ r ∈ acc ∧ newref(r, st) → r = jvmref, validrefs(str, r0 + acc, ty, st), r ∈ r0 + acc, newref(r, st) ⊦ r = jvmref

Rule argument

[VARWITHVARSEQSARG : refs, ()]
